Alexion Pharma (Nasdaq: ALXN) filed to delay Form 10-Q. The company noted the following:

The Audit and Finance Committee of the Board of Directors of Alexion Pharmaceuticals, Inc. (“Company”) is conducting an investigation into allegations that recently have been made by a former employee with respect to the Company’s Soliris sales practices. Specifically, the Audit and Finance Committee is investigating whether Company personnel have engaged in sales practices that were inconsistent with Company policies and procedures and the related disclosure and other considerations raised by such practices. The Audit and Finance Committee has retained outside counsel to assist it in the investigation. At this point in time, the Audit and Finance Committee’s investigation has not identified instances where Soliris orders were not placed by customers for patients or any facts that require the Company to update its previously reported historical results. The Audit and Finance Committee and its counsel are working diligently to complete the investigation, but at this time it is uncertain when this investigation will be complete and what the results of such investigation will be.
